(Plugin) Lightrays in reverse?

Vegas 7.0.

Hi,
Is it possible to get the lightrays to ray inward?
I am trying to make a star-trek like 'star warp effect.

The current lightray plugin is fine for stars warping forward (see image below)

But when stars are coming towards the screen the 'echo lines' of the stars must be behind them.

Any idea on how to get that effect?

Is there some kind of 'video echo' fx plugin available for Vegas?
This effect is also used for superman, while he is moving fast there are trails visible behind his motion.

Thanks,

VMP

Would a horizontal flip (done in the Pan/Crop window) do the trick?

I think he wants to leave tracers.

Hi, I see that pixelan has handy tools for this 'step motion'.

Yes I wanted the stars to have trails behind their motion.

Yes I tried reversing the clip lol, but that is the same as reversing a car running through the sahara,
This would just make the car go backwards following its own sandcloud trail;-)).

you're thinking of it all wrong. you're thinking of it as a 2d image. it's not, it's a movement in 3d space.

solution? :D Pan/crop, motion blur & light rays. use the pan/crop to zoom in, light rays to create streaks & motion blur to smooth them out as you zoom in so it looks like a streak & not a lightray.

Hi TheHappyFriar ,

Actually I am thinking in 3d space.

I have made some 'stars' particles flying towards a camera in 3d virtual world.
Using Maxon Cinema 4D.

See: Stars_toward_screen_Original.wmv

All I needed more was vegas to add the trails behind their movement.
With the help of Pixelan Step Motion I can now do this.

Example with trails: Stars_toward_screen_Warped.wmv

The pan crop etc I do not need to use, it is not a 2d image.

Your pic is wrong all you should have is blurry dots bigger on the outside getting smaller toward the middle infact tiny in the middle all random

Your tonal values are cool brighter dots on the outside darker on the middle almost black in centre of your pic don’t add any streaks to the pic. that will come from light ray plug as you pan in to the pic

then you should of said that! I assumed you had a 2d image, you were using a 2d source. :)

add motion blur in the 3d program. that should solve it.
